This image shows outcrops of light-toned layered rocks in the northern part of Hellas Planitia, the floor of a massive, ancient impact crater.
The floor of Hellas includes the lowest parts of the Martian surface, and has been proposed as the site of ancient lakes or seas.
Light-toned layered rocks are found in many sites on Mars, including much of the north rim of Hellas. They could have been deposited in many ways: volcanic ash, wind-blown sand, river or lake deposits.
Below is a non-narrated HiClip mini, using the enhanced color center swath of the observation. (Less than 1 km across.)
